Issue
When a model package doesn't have
hub_content_arnin its container metadata,model_resolution.pyfalls back to constructing the ARN fromhub_content_nameandhub_content_version. The fallback hardcodedSageMakerPublicHubas the hub name, causing eval jobs to fail withDownstreamServiceUnavailablewhen the base model exists only in a private hub.Fix
use
SAGEMAKER_HUB_NAMEenv var (already used throughout the SDK for hub resolution) to determine the hub name and account in the fallback ARN construction. Falls back toSageMakerPublicHubwith aws account when the env var is not set, preserving existing behavior for public hub models.By submitting this pull request, I confirm that you can use, modify, copy, and redistribute this contribution, under the terms of your choice.
